CONTROL CIRCUIT CONNECTIONS

Control circuit wiring is connected to the terminal block on the top of the operating mechanism (Fig. 20). Connect control wires in accordance with the appropriate wiring diagram shown in Fig. 28 through Fig. 31 in the OPERATION section of this manual.

On the U and MU type breakers, connections to auxiliary contacts are made directly to the auxiliary switch (Fig. 21).

On the L and ML type breakers, connections to auxiliary contacts are made to a terminal block on top of the operating mechanism (Fig. 22).

ADDITIONAL AUXILIARY SWITCH (Optional)

An optional second auxiliary switch may be furnished, located on the right side as viewed from the rear of the breaker.

When a second auxiliary switch is furnished, control wires are connected directly to the switch.

HV6AS specifications

The Toshiba HV6AS is a sophisticated high-voltage IGBT (Insulated Gate Bipolar Transistor) module, primarily designed for demanding applications in industrial and energy sectors. This module stands out due to its superior performance characteristics, which allow it to handle high voltages while delivering optimal efficiency and reliability.

One of the key features of the HV6AS is its high voltage rating, typically around 650V, making it suitable for various applications including motor drives, renewable energy systems, and UPS (Uninterruptible Power Supply) systems. This voltage capacity enables the module to effectively control large power loads, ensuring excellent performance in high-demand environments.

The HV6AS adopts cutting-edge technologies that improve its operational efficiency. The design incorporates advanced thermal management features, which help in enhancing its reliability and lifespan. Integrated with a robust heat sink, the module efficiently dissipates heat generated during operation. This is crucial as increased temperatures can lead to reduced performance and potential failure.

Additionally, the HV6AS utilizes a double-sided cooling structure, which allows for superior thermal conductivity and enables the module to perform optimally in high-temperature conditions. This aspect is particularly important for applications in renewable energy, such as solar inverters, where efficiency and durability are key.

Another notable characteristic of the HV6AS is its fast switching capability. The IGBT technology allows for rapid switching between on/off states. This feature is essential in applications such as pulse-width modulation (PWM), contributing to improved power conversion efficiency. The high switching frequency capability means that systems can operate more efficiently, resulting in lower energy losses.

Toshiba’s HV6AS also focuses on enhancing productivity through simplified circuit design. Its compact form factor means that it can be easily integrated into existing systems, saving space and simplifying installation processes. The module’s compatibility with existing drive technologies allows for seamless upgrades to newer systems without significant changes to the overall architecture.

In summary, the Toshiba HV6AS is a highly versatile IGBT module characterized by its high voltage capability, advanced thermal management, fast switching speed, and compact design. These factors make it an excellent choice for a wide array of high-performance applications in various industries, driving innovation towards more efficient and sustainable power solutions. Whether in industrial automation or renewable energy, the HV6AS sets a benchmark for reliability and effectiveness in power electronics.
